Optional serialization without map tag

[MarcelKlammer]

Hi team,

We find ourselves in the difficult situation to need to support Cardano networks of earlier eras than chang and thus kind of need a way to force serialization without the new map tag.

Would it be possible to implement a flag to support serialization of pre chang?

I've implemented a workaround by dynamically loading an older lib version for earlier era networks.

Hi @MarcelKlammer! Unfortunately we don’t have plans to add it, because we supports previous eras only for deserialization. But yes previous CSL version's is good solution.

But we are open we for PR’s or suggestion of CSL improvements.

Was glad to see you at the summit.

@MarcelKlammer just remind from my side:
FixedTransaction preserves original redeemers format either map or array. So you can just decode tx by FixedTransaction and add necessary signatures by FixedTransaction and everything will be consistent.
